This place is pretty great.
The view alone is worth 4 stars at least!! The apt is actually small but one whole wall is window it really doesn't feel small at all..! And it's facing West so if you're lucky, you get a sunset too!!
We stayed here for a week whilst on business & it suited us just fine. The pool in the condo is bigger than some hotel pools I've seen & was quiet every time I used it.
The neighbourhood itself is nothing special but it's central & pretty easy to get wherever you want to go. Also, it's by the canal, so you can use the canal boat service to get to the old town & Siam Sq. That was a nice surprise & super efficient.
Hotels in Bangkok are quite expensive so I think if you are staying more than a couple of days this place offers good value for money & has everything you need. Oh, and did I mention the view..?!
